3 teams of 3-4 players each. Two teams play for 4 minutes, the third team shoots at a side basket (or waits on the sideline). Teams get a point for each stop. Each possession is 20 seconds (starting from the end of the last play), a foul is automatic loss of play.
When the offence scores, the defenders sprint, touch the far foul line, come back for a pass from coach, and attack. On a stop, the attackers sprint down and back for a pass, and are still on attack.
All teams play each other, 12 minutes in total.
A good conditioner.
